Description

Purpose

To directly show the throughput for the given input, rather than trying to guess the batch dimension and report the value for a single sample, we drop the practice of using the first dimension as the batch for averaging.

Changes:

• .github/workflows/minimal_test.yml: Specify bash shell for PR checkout commands to avoid using PowerShell in Windows.
• torchmeter/statistic.py: modify throughput measuring logic, directly use the reciprocal of the inference latency as the throughput of the model under a given input
